Gitea supports internal TLS termination as well as redirection of
http to https. That may be simpler than terminating in a reverse
proxy. Let's try it.
Also, make the dockerfile match the expectation of the job that
there will be a gitea-init stage.
Also, fix the repository root setting in app.ini.

This creates a jinja-init image based on
https://github.com/ObjectifLibre/jinja-init
We can use this image as an "init container" in k8s to template out
config files using configmaps and secrets.
It also adds a gitea-init Dockerfile, which will require the
jinja-init image to be published first.
